[reportlab-users] Returning PDF to a browser?

You are a little vague on some points, though I think Iget the general gist
of what you are trying to accomplish.  I wrote up a little demo at work that
uses Reportlab to dynamically create a PDF file and send it back to an
Internet Explorer browser as the HTTP response.  Like you, I was getting the
raw PDF showing up in the browser instead of Acrobat reader popping up in
the browser.  The trick to making it work was to observe the headers that
were sent when I typed in the URL of a static PDF file and observe what
headers were returned to the browser.  I believe that the "Accept-Ranges:
bytes" might do the trick for you, though I won't be back to work to double
check until Tuesday due to the holidays here.
